So I thought if I can use a bump map to create, uh, bumps on a surface... I thought I could somehow make it glow/emit light?

Is there a node for that, or maybe there's a method to do that?

    $\begingroup$ the emission node is what you are looking for. $\endgroup$ Sep 29, 2016 at 17:43

You can use an emission node, with a mix shader node (use the map map for the factor input). Now your object will emit light based on the bump map.

  • $\begingroup$ Thing is, I'd like to use the emission along with glossy and anisotropic nodes... kinda new to blender, so still not sure how things work correctly here.... tiny bit too complex.. $\endgroup$ Sep 30, 2016 at 23:39
  • $\begingroup$ @PeterGašperan Try upping the Emission strength. If that doesn't work, something else is wrong. You can send my a .blend file (I'm sending you an email) $\endgroup$ Oct 1, 2016 at 0:13
  • $\begingroup$ I am sorry man, just realised I did not had the email set in the contact form on my homepage, re-installed it just recently and forgot to set it, I appologize greatly! $\endgroup$ Oct 1, 2016 at 11:11
